[SOLVED] multiples Gallery problem in telpmlate 9

HI,

First thing, sorry for my english, I'm french and try to do my best !

I'm using Template 9 and trying to put another galleries in it. I put a new button into the index file and duplicate the gallery.xml file with the new link to the differents pictures files and rename it for new gallery. I did it to with the _portfolio file with new name reffering to new gallery.

the problem is that no matter which gallery I'm clicking on, it's always the same that appears on the portfolio page !
the site is online but I don't know how to install new galleries on this template and the way to make the settings on the files.

The website is here :

Thanks !
